The RU maintains sync holdover with SyncE, in case of PTP GPS or IEEE 1588 loss for 24 hrs. The synchronization
accuracy of SyncE is maintained for 24 hrs under the following condition.
■ SyncE clock at Grandmaster Clock (GM C) synchronizes with 1 pps of PTP.
■ SyncE clock of RU is synchronized with the GM C before loss of PTP.
The RU supports IEEE 1914.1, ITU-T G.826x, G.827x series specified in ORAN-WG4.CUS.0-v02.00.
